gtsam::Basis< DERIVED >::ManifoldEvaluationFunctor< T > Class Template Reference

Detailed Description

template<typename DERIVED>
template<class T>
class gtsam::Basis< DERIVED >::ManifoldEvaluationFunctor< T >

Manifold EvaluationFunctor at a given x, applied to a parameter Matrix.

This functor is used to evaluate a parameterized function at a given scalar value x. When given a specific M*N parameters, returns an M-vector the M corresponding functions at x, possibly with Jacobians wrpt the parameters.

The difference with the VectorEvaluationFunctor is that after computing the M*1 vector xi=F(x;P), with x a scalar and P the M*N parameter vector, we also retract xi back to the T manifold. For example, if T==Rot3, then we first compute a 3-vector xi using x and P, and then map that 3-vector xi back to the Rot3 manifold, yielding a valid 3D rotation.
